Abstract: Systems and methods to control pulse welding are disclosed. An example welding-type system includes: power conversion circuitry configured to convert input power to welding-type power; and control circuitry configured to control the power conversion circuitry to output the welding-type power in a plurality of pulse cycles, each pulse cycle comprising a background phase, a ramp up phase, a peak phase, and a ramp down phase. Controlling the power conversion circuitry involves: during the ramp up phase of the pulse cycles, controlling the power conversion circuitry in a current-controlled mode and switching to controlling the power conversion circuitry in a voltage-controlled mode when a peak transition voltage is reached; and during the ramp down phase of the pulse cycles, controlling the power conversion circuitry in a current-controlled mode and switching to controlling the power conversion circuitry in a voltage-controlled mode when a background transition voltage is reached.

Abstract: An indication is received. The indication is associated with a selection of an identifier on a webpage that at least in part specifies an enhanced content configuration. An enhanced content configuration is set at least in part by using the received indication. The enhanced content configuration can be used to enhance content included on a webpage.

Abstract: Delivering enhanced content is disclosed. An indication of content included on a webpage that is to be enhanced is received. Enhanced content is selected from a specified enhanced content provider previously specified from among a plurality of enhanced content providers. The selected enhanced content is associated with the content to be enhanced. The enhanced content is associated with a display of the webpage.

Abstract: Determining performance of an electronic advertisement is disclosed. Data associated with a measured time of the electronic advertisement is received. The received data is analyzed to determine a performance value of the advertisement. In some cases, the performance value is associated with a time based electronic advertisement cost model.
